I've seen three people having their go up on the plinth, and two of them just stood there grinning, occasionally taking a photo. It was very boring. Don't just stand there occasisionally taking a photo!

like the bumbler said....you can't sustain whimsical or wacky for an hour so i suggest doing something grindingly monotonous that shifts and changes the longer it goes on until it becomes quite transendent......read the yellow pages out...comment on the adverts.....start at A and see how far you go.....if you're funny you could make comments on the businesses.....or just keep reading it. either way.

just don't dress as a bannana and do a five minute dance because then you've got 55 minutes stood on a plinth dressed in 3rd division fancy dress

I seriously considered Stealthy's idea but I'd have to print out sheets and sheets worth of material to last an hour - a little impractical and a big ask as I can't gather and print it out myself.

I think the banana costume is ON. I plan to dance for two 15 minute sessions to banana-themed songs (you know, 4 the kidz) and in between those maybe read out today's David Cameron thread and then just sit for a while reading a broadsheet smoking a pipe (and something else, maybe play with a lightsaber/highlight the problem of puppy trafficking). HOW DELIGHTFULLY ABSURD. Look at that banana, whatever next.

19.00 Annabel, a road safety officer from Leamington Spa, says: "I've decided to wear a school crossing patrol uniform for my hour on the plinth as a thank you to all the wonderful lollipop men and women who do such a fantastic job in ensuring that our children get to school safely each day."

Get some Golf Training balls and a bag of mounted tees. (Training balls are plastic with holes in)... get a friend to distribute buckets to the crowd, get swinging and see how many people can catch the balls

but it would be more interesting for the crowd to ask them to make suggestions forr what you should do.

like "dance for me"
and "squeal like a little piggy" etc

actually I would quite like to dance (but as another userid)

oh if its your space can you invite others up on to the plinthe?
it would be interesting to see if you could get a record for the mnumber of peopl on the plinth

set up a base camp and then set off to climb nelsons column

I dont know if its happened yet, but try to get the police to come up onto the plinthe to arrest you, (If it hasnt already been done) (perhaps you could shout at some passing policemen and insult their hats or something

convince people they will be in a film, or be broadcast and you will be bound to attract huge crowds, encourage them to bay and reach out their hands (for the camera) and that way you will feel what its like to be a rock god
